I've never been able to view these properly on a kindle. Well, last time I tried anyway, is it better now?
A foldable phone may meet his criteria, a Kindle would not.
Most of my books are still physical books. It‘s weird but I often buy books based on their cover.
The real bottleneck is UI, not CPU's.
Modern non-phone CPUs can have TDPs of more than 80W. If your phone did 80W, it would burn your hand. So, forgive me if I'm skeptical of any benchmark that says a phone outperforms a laptop.
You're arguing that the phone CPU can get significantly better performance, do so with less power, and occupy a form factor smaller than what a laptop requires? Why would I not just manufacture a less space-constrained version of this chip (to make it cheaper) and stick it in a laptop?
I Googled the specific benchmark you referenced. I'm not able to find results on it, but one of the top hits was this: https://arstechnica.com/information-technology/2017/04/googl...
(It's not like I can buy laptops any more, since those are all garbage even when I pay $4000 for a supposedly high-end system, so I certainly have spare device money laying around!)
